Abstract

The invention discloses an ultrafiltration membrane assembly integrating catalytic oxidation and carrying a catalyst, and belongs to the field of water pollution treatment equipment. The ultrafiltration membrane assembly comprises a shell composed of an upper sealing cover, a barrel and a lower sealing cover. A hollow fiber ultrafiltration membrane carrying the catalyst and an ultraviolet lamp are fixedly installed in the barrel through an upper tube plate and a lower tube plate. An ultrafiltration water inlet tube, an air inlet scrubbing tube and an ozone adding tube are arranged on the lower sealing cover. Water flow can be pushed to move from bottom to top, the hollow fiber ultrafiltration membrane is made in a shaking state, the catalyst carried on the ultrafiltration membrane is evenly irradiated by ultraviolet light easily, the mass transfer effect between the ultrafiltration membrane carrying the catalyst and ozone and pollutants is enhanced, and therefore the catalytic oxidation effect is enhanced. The ultrafiltration membrane assembly integrates the functions of intercepting suspended solids and colloid, degrading organic pollutants, killing bacteria and the like and provides reliable guarantees for recycling of sewage or nanofiltration and reverse osmosis pretreatment of sewage.

Description

Technical field [0001] The invention belongs to the field of water pollution treatment equipment, and specifically relates to a novel ultrafiltration membrane module. Background technique [0002] The application of ultrafiltration in the treatment of reclaimed water or the pretreatment of nanofiltration and reverse osmosis has been one of the research hotspots in recent years. Reclaimed water treatment or pretreatment of nanofiltration and reverse osmosis requires that the content of impurities in the water such as suspended solids, colloids, organic pollutants and microorganisms is as low as possible. Due to the small pore size of the ultrafiltration membrane, usually between 0.002 and 0.1μm, it can effectively intercept suspended solids, most of the colloids, large molecular weight organics and large-sized microorganisms. The secondary drainage of the sewage treatment plant contains a certain amount of especially soluble organic pollutants that are difficult to biodegrade and...
